DETAILED DESCRIPTION

Sweat band 100 includes a sweat band portion 101, an adjustment portion 103 and one or more attachment portions 105. Sweat band portion 101 is formed from a piece of moisture wicking fabric 111 such as COOLMAX® which is a high tech fabric available from Dupont. This fabric is made from specially engineered polyester fibers with an increased surface area. The surface 101 a of the fabric 111 in contact with skin pulls moisture away from the skin to its opposite surface.

The moisture wicking fabric 111 is fabricated into a flat tube containing a core 107 shown in FIGS. 6, 7, 8, and 9. Core 107 is water absorbing or hydrophilic foam that includes antibacterial and anti-microbial agents to eliminate odor and other unpleasant effects of extended use. The hydrophilic foam is commercially available. The foam has integrated therein water absorbent polymer crystals, so that the foam will absorb moisture such as sweat that is passed through fabric 111. One source of such foam padding is Lendell Manufacturing, Inc.

By using a moisture wicking fabric 111 in combination with hydrophilic foam 107, an extremely comfortable sweat band 100 that provides double moisture removal is provided.

Sweat band portion 101 is formed to contain foam core 107 by folding the fabric 111 over foam pad 107 and closing the ends and top of the fabric 111. In the illustrative embodiment of the invention, closure of the ends and the top is accomplished by sewing. Sweat band portion 101 in the illustrative embodiment is 2 inches high and 19½ inches long. In addition, a longitudinal seam 101 c is sewn to secure the foam pad 107 within sweat band portion 101.

Sweat band portion 101 has affixed proximate to one peripheral edge 101 e adjustment portion or band 103. Band 103 in the illustrative embodiment is 23 inches long and 1¼ inches high. Band 103 is a loop strip of a hook and loop fastener, such as a Velcro™ loop strip. Surface 103 b of band 103 is the loop portion. At one end 103 d of band 103 is affixed a Velcro™ hook portion 103 c. By looping end portion 103 f onto end portion 103 d, the hook portion 103 c engages loop portion surface 103 a.

Surface 101 a of sweat band 101 is the surface of sweat band 100 that is adapted to contact the head of a helmet wearer. Sweat band portion 101 carries two Velcro™ loop portions 101 d on its surface 101 b. As will be understood by those skilled in the art, although two loop portions 101 d are utilized, other numbers of loop portions may also be utilized.

Loop portions 101 d releasably engage hook surface 103 b of band 103 to secure sweat band portion 101 in position parallel to band 103.

A plurality of attachment strips 105 which comprise Velcro™ hook strips 105 are affixed to peripheral edge 101 e of band 103. Each strip 105 has its hook side adjacent to band 103.

The edges of the sweat band portion 101, strips 105, and band 103 are covered by fabric strip 109 that is folded over the edges and sewn to sweat band portion 101, strips 105 and band 103. Fabric strip protects the wearer of sweat band 100 from any rough edges.

Turning now to FIG. 9, a helmet 700 is shown as viewed from the bottom. Helmet 700 includes a protective helmet body 701. A suspension 703 is carried within helmet body 701 and includes a headband 705.

Sweat band 100 is carried in said helmet body 700 proximate suspension 703. The construction of sweat band 100 is as described above.

To install sweat band 100 in helmet 700, sweat band 100 is inserted into helmet 700 with strips 105 entering helmet 700 first. The ends of sweat band portion 100 are placed in the rear portion of helmet 700. As more clearly shown in FIG. 10, strips 105 are positioned between helmet body 701 and suspension 703. Strips 105 are each folded over helmet suspension 703 capturing helmet head band portion between the corresponding strip 105 and band 103. Each strip 105 has its hook portion secured to loop carrying surface 103 b of band 103 thereby affixing sweat band 100 into helmet 700. Closure portions 101 c secure the ends of sweat band portion 101 to band 103.

The helmet is then tried on and Velcro™ strip 103 d is adjusted in position on surface 103 a to adjust for head size
